Key points for operating an air hammer

The core of operating an air hammer must strictly adhere to "standardized procedures + safe cooperation", and fully implement the core principle of "no empty hammering, no cold forging". The specific key points are clearly defined in three stages as follows:

Key points of preparation before operation

Personnel and protection ‌ : All personnel must be certified and wear safety helmets, protective glasses, anti-crush shoes and other labor protection supplies. Non-operating personnel are strictly prohibited from starting the machine.

Equipment status confirmation ‌ : Check that the hammer head, anvil seat and hammer rod have no cracks, and all connecting screws are tightened; The oil passage is unobstructed and the oil level is not lower than the mark on the oil gauge. In winter or after a long period of inuse, first drain the accumulated water in the cylinder and preheat the anvil to around 100℃.

no-load test run ‌ : Place the handle in the no-load position. First, manually rotate the motor and then start it. Let it idle for 1 to 2 minutes. Only after confirming that it operates smoothly without any abnormal noise can the operation be carried out.

Core operation essentials in ⚒️ homework

The ‌ signal in coordination with ‌ : the hammer opener must fully obey the gestures and slogans of the hand clamp operator. Anyone who issues an emergency stop signal must immediately stop the machine.

Forging placement specifications ‌ : Place the forging at the center of the hammer head, hold it firmly, the handle of the clamp must not face the chest or abdomen directly, and fingers must not be placed between the handles of the clamp.

Key points of strike control ‌ : The first hammer must be struck gently. For high-temperature forgings, strike gently to prevent iron slag from splashing. It is strictly prohibited to hammer dry or forge cold parts with a temperature lower than 900℃. The lifting time of the hammer should not exceed 1 second, and the hammer head should not stay on the upper position for more than 1 minute to prevent overheating.

Abnormal handling ‌ : If abnormal vibration, abnormal noise, abnormal hammer head movement or cylinder temperature exceeds 80℃ occurs, stop the machine immediately for inspection.

Closing points after ️ operation

shutdown specification ‌ : Lower the hammer head slowly, place a shims of more than 15 millimeters between the upper and lower anvils, and then cut off the power supply.

Equipment maintenance ‌ : Clean the entire machine, check the shaking parts and the fixation of the anvil seat; The oil in the reducer should be changed every semester, and grease should be added to the journal regularly.
